bokstav i det grekiska alfabetet

AI overview

Sigma (Σ) is the eighteenth letter of the Greek alphabet with two lowercase forms: σ is used in the middle of words, while ς is used at the end of words. This distinction between middle and final forms is unique to sigma among Greek letters and appears in words like "Odysseus," where the two middle sigmas differ visually from the final sigma.
